To all whom 'it may concern.'

Be it known that I, NrcoLL C. Onno, a

citizen of the United States, and a. resident of Middletown, in thecounty of Orange-and State .of New York, have invented certain new and,.useful Improvements in Automobile-Horns,of whiehthe followingis aspeciiicaticn. l. i

Myinvention is an improvement `in automobile horns, and has .for itsobject the ,PrO- vision vot mechanism for initiating a series oflrapidly succeeding air vibrations, together .with .mechanism ,forcontrolling and 'modulating vthe ivibrations to produce sound Wavesresembling the human voice as it is modulated by Vthe lips; y

V-In .the drawings :#Figure l is a Sect-i911 on 'the line 1 1 of Fig. 2,Fig. 2 is ,a section on the line 2-2 of Fig. '1, Fig. 13 is a detail..perspective view of the valve actuating mechanism, and Fig. 4 isatransverse section of the `inte-nsiier showingsI modified ,form ofvalve.

1 I In qthe present embodiment of the ,1nven' tion, atwo partcasing isprovided, consisting of thesections 1 and 2each of the said sectionsbeing lapproximately'cup shaped and ittingatfitsedges against theothersection. Each section 1 tand 2 is provided Awith a lateral iange 3 and 4respectively, and a disk 5 having ac entral laterallyextendingnipple 6'is secured `to .the dtges by Ill-Cans of screws ,7. I

The disk 5 is provided withva lateral mar ginal flange 8 .extendinginthe opposite di rectio'niothe lnipple 6, and the saidilange'itsoutsideoftheanges and 4 ofthe casing sections. A' diaphragm 9 isarrpn ed between .the disk A5A ,and @the .flangs'i an., fl, the said.diaphragm extending lfiero-SS. the

' opening vatftiiat endof =t-'bet ;afsfing adje# cent to the d1sk,5,and,the s aid diaphragm 9'is held inplace by the screws 7 before mentioned.Gaskets .1.0fand 11 are arranged o n opposite sides of ,the d.inph-ragni Ibetween' the 'anges 3 and .4 'and the disk and a .lug orprojection 12 is secu'redito thecenter of the diaphragm, the saidlpgfbeing rounded from side t0 side as vshown moreparticularlyinFig.1.`-"y 1 A supportingr frame .consisting of 'a base 13andlaterally extending;` arms 14 isadjustably securedtogthe casingsection 2, by means of screws- 1 5,'which ,are passed through enlargedopenings 1,6 inthe casing'ction, and are .threaded into l,the base `13toAadjnstably ever the position of the` supporting.frame 13.

A disk or Wheel- 18 is secured to a stub shaft` 19, Whose ends arejournaled .in the base 13 of the supporting frame and in a plate 20secured to the arms 14 and held in spaced relation by the said arms. Thewheel v18 is provided with a plurality of arcshaped cuts or notches 21,and the junction `of the said cuts or notches forniteeth .22,

the .said teeth being adapted to engage the vlng 1 2, before mentioned,to produce` a snccession of vibrations of thediaphragm when the wheel isturned.

A pinion 32 is secured to the stubshaft 19, and the said pinion is inmeslrwith fa gear Wheel 21 on an operating shaft 25, which is journaledin a bushing 26, extending laterally from the base 13 of the-supportingframe through an opening 27 in the section 2. The Aopening 27 is ofgreater diameter than `the bushing', so that the bushing will notinterfere with the adjustment of the supporting frame, before mentioned.

A crank 28 is secured to theshnt 25 at the 'outer end of the bnshing andit will be evi dent that when the crank is turned, the wheel 1S will berotated rapidly to produce a series of rapid contacts between the teeth22 and the lug 12, whereby to vibrate the diaphragm 9.

An intensifier in the'shape of a horn 29 of tapering form, and vofsuitable material as for instance metal, has its inner end engaged withthe nipple tithe said inner end being slip-pcd outside of Ithe nipple tohold the horn in place.

horn is provided with a bead 30 for stiienin'g the same', and an annularframe 31 is arranged transverselyof the horn somewhat nearer the outerend than the inner.
